If two straight lines are coinciding with each other, then the number of points of intersection is/are
Show answer & explanation
Correct answer: A
Explanation
The correct answer is option 1 i.e. infinitely many points of intersection.
If two straight lines coincide (meaning they are the same line), they have infinitely many points in common. Every point on one line is also on the other. So, they intersect at an infinite number of points.
Therefore, the number of points of intersection is infinitely many points of intersection.
